A laboratory ultracentrifuge is designed to produce a centripetal acceleration of 4.0 106 g at a distance of 5.00 cm from the axis. What angular velocity in rev/min is required?

  • physics - ,

    Require R*w^2 = 4*10^6 g
    Then solve for w, which will be in radians per second.
    Then convert w to rpm.
    Use an ^ before your exponents

    R = 0.05 m
    g = 9.8 m/s^2

  • physics - ,

    Thank you drwls...
    I got 2.7e6 but apparently that is incorrect.
